` I Application filed May 27,

This invention relates to a display apparatus of improved construction and operation.

It is an object of the invention to provide a device which will possess attractive advertising qualities, and which will embody an extremely simple and economical form of construction operating at minimum expense over long periods of time with freedom from mechanical difficulty and manual attention.

It is a further object of the invention to provide a display device the display features of which may be readily renewed when it is desired to do so. A

Other objects of theinvention will in part be obvious and will in part appear hereinn after.

.The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the inventionl reference should be had to the following detaileddescription taken in connection withl the accompanying drawings, in which Figure .1 is a plan view of one form of display device embodying the construction of the present invention, the display panel thereof being broken away to disclose the underlying structure;

Fig. 2 is an end elevation of the device as shown in Fig. l;

Fig. 3 is a sectional view of the apparatus as shown in Fig. 2;

Fig. 4 is a plan view of nism;

Fig. 5 is a fragmentary partly sectional side view, showing certain details .of this mechanism;

Fig. 6 is a transverse `view of one of the elementsas shown in Fig. 5; and

Fig. 7 showsV anv optional form of drive mechanism.

In'these several views the numerallO indicates the base of the apparatus, which in its present form simulates in appearance a book opened adjacent its central portion. According to the present embodiment of the invention, brackets 11 and 12 are mounted adjacent the upper and lower book ends and centrally of the side edges thereof, the first bracketl supporting a stub shaft 13, anda similar shaft being provided'by a screw 14 the driving mecha- DISPLAY DEVICE.

reason that by so doing the rea-r edge of the leaf 16 may be reinforced, for example, by a U-shaped metallic stripA 17 having outstanding portions 18, as a consequence of which, when the tube is detached Vfrom the book, the leaf or display panel may be readily removed from the tube and replaced, these elements,

however, normally being fixed with respect to each other'. As shown, the lower end of the tube is screw-threaded for engagement with the threads of the shank of the screw 14, and the upper end of the same receives the stub shaft 13, which carries vat its outer end a pin 19.. Asa consequence, it will be understood that the tube may be readily dismounted by Asimply detaching the screw 14 and exerting a pull upon the tube towards the lower end of the book, and mounting of the same being accomplished by a reversal of this procedure. When in position the tube will be prevented from movement with respect to the stubvshaft 13, and if the latter isoscillated the tube, together with the leaf carried thereby, willbe swung back and forth so that the opposite side faces thereof willbe displayed alternately.

With a view to driving the shaft 13 motor 20 of any suitable type maybe mountedl for example, below the base andpreferably enclosed within a protective casing 21. This motor rotates a worm shaft 22 by means of a suitable drive 23, this shaftfin turn driving a worm wheel 24, which through reduction gearing 25 rotates a crank 26 when the motor is operating. Secured to the outer end of this crank is a rod 27 slotted as at 28, and a crank 29 mounts a pin 30 extending within this slot, this latter crank being in turn se curedto a shaft 31 mounting a pinion 32 in mesh with a gear 33 secured to the shaft 13. As a result, it will be understood that when the motor 2O is energized the crank 26 will rotate, reciprocating the rodl 27, which, dur,-

v ing the :final stages of its stroke -in one direction, will have the end wall of the slot 23 contacting with the pin 30, thus rocking the llO l these shafts.

crank 29 in one direction, and which, further, during its final stages of movement in the opposite direction, Vwill engage similarly the pin of the crank 29 to return it to its initial position. Thus, withthe motor operating continuously, the pinion 33 and the shaft 13 secured thereto will be oscillated in such a manner that the leaf connected with the shaft will have its first face displayed for a sufficiently long period of time for the observer to peruse the advertising matter displayed upon said face. Subsequently, the panel will be swung quickly and the rear face thereof will be displayed ina manner similar to the first face. During such periods of display it will be obvious that lost motion will be occurring between the crank and the slot of the rod 27.

If desired, both of the upper faces of 'the base l0 may simulate in appearance the pages of a book, or, as has been shown, one of the halves of the base may be recessed suitably as at 34 to provide what is commonly known as a shadow box, which may be suitably illaminated. Vhere a construction of this nature is utilized the display panel or leaf acts as a cover for the shadow boX, alternately:

'i Fig. 7, each corresponding to the stub shaft 13, and mounting gears 3G one upon each of The teeth of these gearsare interrupted and they are engaged by the teeth 37 of the pinion gear 38, the latter in the present embodiment having the major portion of its periphery unformed, and the series of teeth being just sucient to assure a proper operation of the shafts 35. It will be obvious that as the shaft 31 which supports the pinion 38 is moved in one direction, the first gear 36 will be turned, carrying with it its shaft, subsequently to which the operation of the second and third pinions follows. Upon the shaft 3l reversing its direction of rotation, the gears 36 will be returned to their initial position,4 carrying with them the leaves connected with their shafts 35. It is here to be noted that the unformedv periphery of the pinion 38 preferably cooperates with recessed portions formed immediately to the rear of the series of teeth in the pin- .ions 36. As a consequence, the latter, when theirjteethare not engaged by the teeth 37, are locked against movement.

In both of the illustrated forms of the invention the display panel or panels are turned and re-turned, and this is accomplished in a manner consistent with the objects specifically enumerated previously.

Since certain changes may be made in the above construction, and different embodiments of the invention could be made, without departing from the scope thereof, it is intended that all matter'contained in the above description or shown in the accom- `panying drawings shall be interpreted as illustrative and not in a limiting sense.

lt is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
